I just got a question in the review queue that, though poor, I thought was potentially salvageable via editing. However when I clicked the Edit button I got the deleted post error. Since the post was gone, I clicked I'm Done (what is there do do with a deleted post?) only to get the review audit failed message instead.
The current behavior is also problematic in that, now that I know about it, it's a risk-free way to check if a question is an audit and not an actual review. That allows me or anyone else who knows about it to detect audits without having to recognize that the question is bad.
